*Who really needs to know algebra or Pythagorus? Where will that help in daily life really.
I was crap at maths but passed.
NEVER NEEDED anything other than adding, subtracting and multiplication*
But maybe if you were comfortable with other maths skills you would have found those of use in every day life too.
I admit that I have a job where mathematical skills are pretty key.
However, even outside of a professional life I do use those skills.
A PP mentioned cooking - absolutely!
Simple equations often used when I am working out a time plan to make sure all the components of a meal are ready at the right time.
Ratios when I am scaling a recipe up or down.
Even geometry. I have used the formula for finding the area of a circle when working out how many 7 inch pizzas I would get from the dough when the recipe expected you to be making 10 inch.
In fact calculating volumes generally when using different sizes of cake tins.
Pythagoras theorem useful in many crafts.
In fact I remember as a young teen helping my Dad build a hen house. Dad left school at 14 in the 1930s so didn't really have much secondary education and certainly no formal qualifications but he did do an apprenticeship and became a very skilled builder. Anyway he explained to me it was very important that the corners were "square", i.e. right angles, and that you could check this by measuring 3 feet down one side and making a mark, 4 feet down the other - well you get the idea. Anyway I recognised it as Pythagoras of course and told Dad I had done it at school. He was very interested. He hadn't heard of Pythagoras theorem but had been using it regularly for the last 40 years!
